摘要： A speech synthesis method subjects a reference speech signal to windowing to extract a speech pitch wave having a window function of a window length double a pitch period of the reference speech signal from the reference speech signal. A linear prediction coefficient is generated by subjecting the reference speech signal to a linear prediction analysis. The speech pitch wave is subjected to inverse-filtering based on the linear prediction coefficient to produce a residual pitch wave, which is then stored as information of a speech synthesis unit in a voiced period in a storage. Speech using the information of the speech synthesis unit is then synthesized.

摘要： A speech synthesis apparatus synthesize a speech signal by filtering a speech source signal through a synthesis filter. A speech source signal codebook stores a plurality of speech source signals as a code vector. A unit dictionary memory stores a plurality of synthesis units corresponding to phonemic symbols, each synthesis unit comprising an index of the code vector in the speech source codebook and a shift number for the code vector to decode the speech source signal. A unit selection section selects a synthesis unit corresponding to phonemic symbols to be synthesized from the unit dictionary memory. A synthesis unit decoder selects the code vector corresponding to the index in the synthesis unit from the speech source signal codebook, and shifts the code vector according to the shift number in the synthesis unit.

摘要： This invention provides a novel speech coding system which recursively executes a filter-applied "Toeplitz characteristic" by causing a drive signal (i.e., an excitation signal) to be converted into a "Toeplitz matrix" when detecting a pitch period in which distortion of the input vector and the vector subsequent to the application of filter-applied computation to the drive signal vector in the pitch forecast called either "closed loop" or "compatible code book" is minimized. The vector quantization method substantially making up the speech coding system of the invention is characteristically used by the system.
